'ADVERTIS ING DEVICE F iled Oct. 5, 1928 a Sheets-Sheet 1 ATTORNEY May27, 1930. w M. c. CHAPMAN ADVERTISING DEVICE Filed 001:. 1928 3Sheets-Sheet 5 ATTORNEY Patented May 27, 133% UNITED STATES meant AT NT-OFFICE ADVERTISING nnvion Application filed October 5,1928. Serial No.310,558.

This invention relates to advertising devises of the intermittent rotaryoperable type.

An object of the invention comprehends a drum bearing advertising matteradapted to be exposed at predetermined intervals through a sightopening.

Another object of the invention contemplates an operating mechanism forthe drum whereby the advertising matter may be shifted in juxtapositionto the sight opening.

More specifically stated the drum and operating means therefor aremounted within a cabinet of suitable design including the sight opening.

With the above and other objects in View, the invention further consistsof the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a sectional view taken on line 11 of Figure2.

Figure 2 is a sectional view taken on line 22 of Figure 1.

Figure 3 is a horizontal sectional view taken through the cabinet anddrum on line 3-3 of Figure 2.

Figure 4 is a detail sectional'view taken through a bracket mounting fora train of gears online 4-4 of Figure 1.

Figure 5 is a detail sectional view taken on line 55 of Figure 1 througha stop mechanism for the drum. 7

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the reference character 10indicates generally a cabinet of any desired shape carried upon a base11. A dome 12, carried upon the upper periphery of the cabinet, isadapted to close the uppermost end thereof.

A drum, having ends 13 and 14 respectively and common sides 15 of anynumber and shape, but in this instance are seven in number and ofelongated shape to conform to the angularity of the ends and to theshapes of the outer surfaces thereof. A bearing 16', carried upon theupper side of the base 11 within the cabinet 10, is adapted to seat acompanion bearing member 17 included upon the under surface of the end13 of the drum and having. connection with the lowermost projecting endof a standard 18 extended centrally of the longitudinal axis of saiddrum. The standard being keyed within each'of the ends 13 and 14 tofacilitate simultaneous operation therewith.

Seated upon the upper side of a shelf 19 horizontally disposed withinthe cabinet 10 m above the end 14 of the aforementioned drum is the basemember 20 of spaced parallel arms 21. Said arms are adapted toaccommodate the enlarged end 22'of a bracket member 23 horizontallydisposed from a motor 24. A pulley wheel '25, drivenby the motor 24,drives a belt or other endless connection, such as indicated at 26,trained overa relatively large sheave 27. Aspur gear 28, carried Z9 uponthe lowermost projecting end of the shaft 29 for the sheave 27, ismeshingly engaged with a complemental gear member 30, having a piniongear 31 upstanding therefrom.'

A relatively large ring gear 32, journaled upon an upstandingstub shaft33, carried upon the upper'side of the shelf 19 meshingly engaged withthe pinion 31, issimultaneously operablein conjunction with a one toothgear 34 adapted for selective engagement with a drum gear 35 keyed tothe upwardly projecting end of the standard 18.

The side edges of each of the sides 15 are rolled, as at 36, togrippingly retain the adjacent side edges of placards 37' adapted tocarry any desired advertising matter in the nature of pictures orprinted matter. The cabinet 10 is in turn provided with a transparentpanel 38 corresponding in size to that of the dimensions of the placardsin order that the advertising matter carriedby the latter may beefiectively exhibited therethrough. V

As evidenced by the illustration of my invention in Figure 1 of thedrawings. it is noted that the one tooth gear'34 is adapted forselective engagement with the drum gear 35 whereby the latter will beturned the distance of two teeth each time the one tooth 109 of the gear34 engages same. The distance of When disengaged from the operatingmechatwo teeth upon the drum gear 35 is equivalent msm to preservealignment of the placards to that of the width of one of the sides 15within the sight opening.

for the drum, whereby the one tooth gear 34 will shift another of theplacards behind the sight opening and panel in the cabinet each time thedrum gear 35 is engaged.

An angle bracket 39, carried by and depending from the shelf 19, carriesa curved spring finger upon the depending extremity thereof. Anenlargement 41, mounted upon the outer surface and adjacent thelowermost end of the curved spring finger 40, is adapted to frictionallyengage the upstanding wall of a recessed portion 42 in the upper side ofthe end 14 of the drum. An adjusting element 43, horizontally disposedwithin the depending end of the angle bracket 39, is

adapted for engagement at one end with the inner side of the dependingcurved spring finger 40 to regulate tension of the latter against theupstanding wall of the recessed portion 42 in the upper side of the end14 of the drum. The spring finger will prevent the faces or sides of thedrum from being shifted past the sight opening.

If desired, an incandescent lamp bulb may be included within the cabinetimmediately above the sight opening therefor to illumi nate the placardsat night. By the same token. an intermittent switch may be included incircuit with the bulb to flash same each time another of the placards isexhibited.

The invention may be set up for use in public squares and parks andother places of general interest where people are known to congregate.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is here in reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having thus described the invention; what is claimed is:

An advertising device comprising a cabinet having a sight opening in oneside and a dome upon its top. a drum included within the cabinet havinga shaft journaled within the bottom thereof. side portions for the drumbeing adapted for disposition in parallelism with that of the sightopening, gripping elements carried upon the side edges of the drum sideportions to retain placards thereagainst. an operating mechanismincluded within the cabinet and dome therefor being ada ted tointermittently rotate the shaft toiexhibit the placards through thesight opening, said drum having a recess within one end. a spring fingerconstituting a .stop carried by and extending from the adjacent portionof the dome and projecting for an appreciable dis tance within'therecess and frictionally engaging the upstanding wall of the latter, and

an adjusting element for said finger whereby the drum will be restrictedas to movement In testimony whereof I aflix my signature.
